STRAW-STACKER.

SPECIFICATION forming part Of Letters Patent No. 628,144, dated July 4, 1899.

Applioationfiled March 21, 1899. Serial No. 709,876. (No model.)

To all whom it may concern:

Be it known that I, EDWARD GROVEN, a citizen of theUnited States of America, and a resident of Bagley, in the county of Bel trami and State of Minnesota, have invented certain new and useful Improvements in Straw-Stackers, of which the following is a specification.

My invention seeks to provide a simple and efficient device by which the straw and chaff thrown out by a threshing-machine may be deposited in a stack automatically; and it consists in certain novel features hereinafter described and claimed.

In the annexed drawings, Figure l is a side elevation of my improved device. Fig.2 is a longitudinal section of the same. Fig. 3 is a transverse section taken on the line a: a: of Fig. 1, and Fig. 4 is a detail view showing the manner of securing the fan-box in position and securing the fan.

Referring more particularly to the drawings, A designates the rear end of a threshingmachine, which may be of any desired style, and is shown merely in order that a proper understanding of my invention may be readily had. Secured to and extending upward from the lower rear corners of the threshingmachine are two side rails or bars B, which are maintained in parallel positions by a plate 0, secured to and extendingbetween them throughout nearly their entire length. This plate 0 is given an upward inclination slightly greater than that of the side rails and serves as a support for an endless conveyerbelt D. This belt D runs over and is driven by pulleys E, secured on shafts F, which are journaled in the side rails at or near the upper and lower ends of the same, as clearly shown. Motion is imparted to the belt by means of a band running from the fan-shaft of the threshing-machine and around a bandpulley G on the lower shaft F. Fitting against the upper ends of the side rails is a box H, consisting of side, top, and bottom plates. The side plates are provided with extensions 1, extending partly under the side rails B, and the bottom plate is carried around these extensions in a semicircular form, as shown, thereby forming a fan-casing. The upper or outer ends of the top and bottom plates are brought close together, so as to form a narrow escape-opening, and consequently tend to counteract the spreading tendency of the discharged refuse. Resting on the top edges of the side rails B- and extending over the top plates of the box H are strips J, in which, near the outer or upper ends thereof, is journaled a transverse shaft K, on which a beater L, triangular in cross-section, is secured. This beater, it will be noticed, is just over the upper end of the conveyor-belt and extends across the entrance to the box H. Clogging of the straw under the top plate of the said box is consequently overcome by reason of the beater in its revolutions striking against and agitating the straw and throwing it out into the box. The box and the side rails and strips are secured firmly together by brace or bolt rods M, engaging the upper edges of the strips and inserted through lugs on the bottom plate of the box. Secured on these brace bolts or rods are journal-boxes, in which a fan-shaft N is mounted, the said shaft being disposed coincidentally with the centers of the extensions I, so that the fan 0 will be under the oonveyer-belt, and consequently will not,when in use, blow the straw upward. The fan-shaftis set in motion by a belt from the threshing-machine cylinder and the beatershaft is driven from the fan-shaft.

It will be readily seen from the foregoing description, taken in connection with the accompanying drawings, that I have provided a device which is very simple in construction. The operation is thought to be obvious. The straw and chaff is thrown out by the threshing-machine onto the conveyer-belt and by it carried up to and deposited in the fan-box in front of the fan. The rotation of the fan creates a current of air which forces the refuse out of the box and on to the stack. The device has no long, heavy, and cumbersome tube, is free of all complicated arrangements of parts, and is positive and certain in its action.

Having thus described my invention,what I claim, and desire to secure by Letters Patent, is

l. The combination of the endless conveyer,a triangular beater arranged j ust above the upper end of the conveyer and adapted to impinge upon the straw on the conveyer, a box at the upper end of the conveyer having an extension projecting under the conveyor,

and a fan mounted in said extension below the conveyer projecting into the box beyond the fan whereby the straw is deposited in the box in front of the fan and the current of air from the fan is prevented from passing through the conveyer.

2. The combination of the side rails, an endless oonveyer mounted between the same, a box fitted against the upper ends of the side rails and consisting essentially of side plates having extensions projecting under'the side rails. and bottom plate carried around the edges of said extensions in a semicircular form, strips J resting on the top edges of the EDWARD GROVEN.
